To all whom if 'may concern .1

Beit known that I, HERMAN (y). Printen, a citizen of the United States, residing at Blue Island, in the county ci Cook and the State of Illinois, have invented a certain new and useful improvement i `in. Railroad-Car Trucks, olf which the following is a full.,`

clear, concise, and exact description.

My invention relates to ltrucls `ft'or railroad cars and includes three point supports for the truck holsters andthe employment of IU bolts as component members of the truck side trames. These U bolts are desir- `ably `also arranged to assemble the journal boxes with the side frames.

rPhe invention.` in all oi' its characteristics, will be explained in connection vwith the ac- 'coinpanying drawings in which Figi side view of a car truck made in accordance with the preferred embodiment of the invention; Fig. 2 is a View taken from beneath thetruclr as shown in Fig. l, parts being shown in section and parts being removed;

and Fig. 3 is a perspective view of afblock `which enters into the construction shown in Figs. l and 2.

Like parts are indicated by similar `char-- acters of reference throughout the different iigures.

The truck side frame illustrated includes an upper arch bar 1, a lower arch bar 2, ,andl

between the arch bars and in the general` plane thereof. In the construction otFig.

i" these springs are seated directly upon the 1 `lower arch bar. The nprightl` `U bolt 8, which is not a novel part of the' present invention, forming the subject matter of another application, ySerial No. 692,369, filed Feb. l2, 1924,*serves to define the positions i of springs 5 and 7 and has its base below the/lower arch ba-r and its sides passing through both of the arch bars with which the` bolt is held in assembly" by* means of its nuts `9` threaded upon the .upper :ends-of `the bolt sides.A bolstenguide .are i formed with` verticalbores which are coaxial with the bores of the upright springs 5 7. The sides of the bolt @are passed through aligned bores of `the guide bars and said springs, this U bolt` being `inthe general plane of the truckA side iframe. The truck bolster extends between thesides of the U bolt `8 and is` supported by the ysprings 5, 6 and 7 and-has Wings ll `at its bottom through which the sides of thebolt pass, .i

these wings being interposed between the bolster i guide bars and springs and 7 underlying these guide .harsThe interina diate upright truck bolster supporting spring `(i and its associate springs` 5., 7 are so related that their axes `and the aires of the sides ot the U bolt 8 are inr a cominonvertical ,plane that also incliides the corresponding side frame. The bolster` is guided in its movements the side portions thereof. lwhich,

are above thebolsterivings il, and the `contiguous bolster guide portions.` `The sides of the U bolt S and the wings 1l ofthe bolster also taire part in guidingfthebolster. The brake hangers l2, 13 are carried by the supports la, 15 integrally cast with "the guide bars Sand rllhesesupports orin the subject of' another application, Serialhlo. 6,92,- 371, filed Feb. l2, 1924. `The brake members 16 and 1T are carried at the lower .ends of the brake hangers to be in normal relation with Vthe Wheels i8, i9. that are disposed at the ends of thecontiguous vSide frame and whose axles 2O engage the bearings Qi which are housed within `the journal'boxes` Q2 suit--v ably assembled with theside `frame.

l/Vhen `construction of Figs. l and 2p.v is employed, a block 23` is interposed between the baise of `U bolt 8 and the bottom arch bar, there being a groove 24 in the bottom olf this block andextending longitudinally of thesidefraine, and receiving the base of the U bolt 8'. i

The means Vshown for assembling-fthe journal boxes with the contiguous'` side frame includes `twoiranie members the forni of other U bolts, whose bases-26ers received in the groovesQ? thatextend tra-nsversely through the block 23 andV intersect the longitudinal groove 24 thisv` block. The grooves 27 are just suciently deeper than the groove 24 to enable the Ufibolt bases 26 to be held tightly by the base of the U bolt y8 betweenthis' U bolt basel and y the bloeit `2a The symmetrically related pairs of the U bolt sides 28, 29 continue from their U bolt bases longitudinally ot the contiguous side frame of the truck and beneath the same, and beneath the journal boxes 22. One of the sides 28 of each of these underlying U bolts is bent near its end at an angle and passes upwardly through the ears 30 upon the side of the adjacent journal box 22 which is nearer the truck bolster and also through the approached ends of the two arch bars that overlie the journal box. The complemental. U bolt side 29 of each underlying U bolt is continued below its associate journal box to the opposite side-thereof and is bent to pass upwardly through the ears 31 upon this side of such journal box and thence through the approached ends of the arch bars. The bolt nuts 32 are screwed upon the upper ends of the upright portions of the Ubolt sides 28, 29 to clamp the arch bars together' and also to clamp the journal boxes between the arch bars and the contiguous U bolt sides 28. 2f) that thus are in supporting relation to the journal boxes. The symmetrically related underlying U bolts whose sides 29 thus take part in assembling` the ends of the two arch bars and the journal boxes are so shaped and disposed as also to constitute lower members ot the corresponding side frame. The upwardly bent end portions of these underlying` U bolts are spaced apart, longitudinally of the contiguous side frame, as has been said in other words, to deiine with the ends of the arch bars and the horizontal portions of these U bolt sides, spaces to rece-ive the journal boxes.

It is obvious that changes may be made without departing from the spirit of my invention.
